Another 80's or 90's animated movie mystery
So this will probably plague me for the rest of my life until I get an answer.
This was something that I bought on tape and used to watch as a child... it was a movie that reminded me a bit of snow white except a lot of elements were different. I lost the movie a long time a go when I moved so I'm sorry for the lack of details. Most vivid was possible the film company that sponsored it. Their logo was a red oval image, with like longitudinal and latitudinal lines for the earth. I could I sworn it was called world studios. It wasn't the only time I've seen this company for a movie. Anyone recall? And now a few details about the film that have stuck... there's an element of a quest to find someone, perhaps a princess. Also, there's also this part where there are little kids, with different personalities singing, which reminded me a lot of the seven dwarfs, which led me to think it had to do with some adaptation of snow white. Again, there is definitely singing and definitely fantasy. That's all I can remember.
Any help? Thanks!
